thereby.

A further object is to provide an articlel of this character in whichthe filter element may be constructed in a separate detachable unit foruse in connection with conventional oil cups already in use, and whichmay be easily and quickly applied, or kremoved for cleaning andreplacement of parts.

A further object is to provide in an article of this character afiltering element provided with a protective platewhich will preventaccidental puncture ofthe filter element by the spout of an oil can whenthe spout is inserted through the filler opening of the cup to fill thesame.

With the above and other objects in view, the invention resides in thecombination and arrangement of parts as hereinafter set forth, shown inthe drawing, described and claimed, it being understood that changes inthe precise embodiment of the invention may be made within the scope ofwhat is claimed without departing from the spirit of the invention. i

In the drawing:

Referring to the drawing, the numeral 1 designates the cap member, 2`the base member, 3 the cylindrical glass sides, and 4L the axiallydisposed tube of a conventional form of sight feed oil cup having screwthreaded connectionswith `the base and cap members for holding saidparts together. Extending through nthe cap and tube is the usualadjustable needle valve cooperating withthe discharge aperture in thebase of the cup, and operating to control the .discharge of oil from thecup, all for the purpose and inthe manner well understood in the art. iIn the preferred form oflthe filter unit which is designed to be easilyattachable to and detachable from an oil cup of t-he general characterdescribed, 'thesame comprises a cylindrical body member 5 provided witha screen 6 forming the bottom thereof, and which bottom carries anupwardly extending tubular member 7, with which an aperture 8 in thebottom member coincides and which aperture and tube permit the holder tobe positioned withinthe cup with the tube 4 of t-he cup extendingtherethrough.` The holder is further provided at its upper edge with alaterally and outwardly extending flange 9 adapted to rest upon theupper edge of the glass cylinder 3 of the cup, which thus supports thefilterl unit dependent within the cup. As shown, a packing ring 10 maybe interposed between the flange "9 and the upper edge oftheglasscylinder, and another packing ring 11 between said flange andthe cap member l, wherebya tight joint may be effected between saidparts when the cap is firmly drawn to place. The cap isdrawn to place byits threaded connection l2 with the tube 4', as in the conventionalmanner, so that by turning the cap the same will be drawn downwardly toeffect a tight joint between the holder flange 9 and the cylinder edge.

v Disposed upon the screen bottom 6 of the holder is: a centrallyapertured disk 13 of PATENfn OFFICE: f
